Colloid Journal is an international peer-reviewed journal that publishes the results of research in the area of physics and chemistry of the disperse state of matter and interfacial phenomena. The journal covers experimental and theoretical works on a great variety of colloid and surface phenomena: the structure and properties of interfaces; adsorption phenomena and structure of adsorption layers of surfactants; capillary phenomena; wetting films; wetting and spreading; and detergency. The formation of colloid systems, their molecular-kinetic and optical properties, surface forces, interaction of colloidal particles, stabilization, and criteria of stability of disperse systems (lyosols and aerosols, suspensions, emulsions, foams, and micellar systems) are also topics of the journal. Colloid Journal also includes the electrosurface and electrokinetic phenomena, i.e., phenomena dealing with the existence of diffusion layers of molecules and ions in the vicinity of the interface. The journal publishes reviews and original articles and welcomes manuscripts from all countries. Peer review and editorial policy The journal follows the Springer Nature Peer Review Policy, Process and Guidance, Springer Nature Journal Editors' Code of Conduct, and COPE's Ethical Guidelines for Peer-reviewers. Approximately 10% of the manuscripts are rejected without review based on formal criteria as they do not comply with the submission guidelines. Each manuscript is assigned to 2–5 peer reviewers. The journal follows a single-blind reviewing procedure. The average period from submission to the first decision is usually at most 15 days. The approximate rejection rate is 30%. The final decision on the acceptance of a manuscript for publication is made by the responsible Editor. If Editors, including the Editor-in-Chief, publish in the journal, they do not participate in the decision-making process for manuscripts where they are listed as co-authors. Special issues published in the journal follow the same procedures as all other issues. If not stated otherwise, special issues are prepared by the members of the editorial board without guest editors.
